我终于实现了@A_nto2 建议的解决方案,它完全实现了我想要的:我现在有一个 Windows 服务来监视进程列表,每当它们关闭时,它们会使用活动用户的凭据和会话再次自动启动,所以 GUI 是可见的。
但是,由于他发布的链接显示了 VC++ 代码,因此我将我的 C# 实现分享给任何处理相同问题的人:

以下是代码的调用方式:
var process = new Process();
process.StartInfo = new ProcessStartInfo { FileName = @"C:\path-to\target.exe", Arguments = "-arg1 -arg2" };
process.StartAsActiveUser();
希望能帮助到你!
